我使用 collectionfs 在我的应用程序中存储文件。
我将随 collectionfs 提供的大部分自述代码复制并粘贴到我的应用程序中，并添加了
{{cfsFileUrl "default1"}}
到我的文件列表。一切都在我的本地机器上运行。
当我部署到 ???.meteor.com 时出现问题
mrt deploy ???.meteor.com
我可以上传和下载图片，还可以从 cfsFileUrl 显示一个 url，
但：
当我访问该网址时，我收到错误 404。
我的代码：client.html
<body>
{{loginButtons}}
{{>queueControl}}
<br>ta
<br>
{{>fileTable}}
</body>
<template name="queueControl">
<h3>Select file(s) to upload:</h3>
<input name="files" type="file" class="fileUploader" multiple>
</template>
<template name="fileTable">
{{#each files}}
{{cfsDownloadButton "ContactsFS" class="btn btn-primary btn-mini" content=filename}}<br>
<img src="{{cfsFileUrl "default1"}}">
{{/each}}
</template>
客户端.js
ContactsFS = new CollectionFS('contacts', { autopublish: false });
Deps.autorun(function () {
Meteor.subscribe('myContactsFiles');
});
Template.queueControl.events({
'change .fileUploader': function (e) {
var files = e.target.files;
for (var i = 0, f; f = files[i]; i++) {
ContactsFS.storeFile(f);
}
}
});
Template.fileTable.files = function() {
//show all files that have been published to the client, with most recently uploaded first
return ContactsFS.find({}, { sort: { uploadDate:-1 } });
};
服务器.js
ContactsFS = new CollectionFS('contacts', { autopublish: false });
Meteor.publish('myContactsFiles', function() {
if (this.userId) {
return ContactsFS.find({ owner: this.userId }, { limit: 30 });
}
});
ContactsFS.allow({
insert: function(userId, file) { return userId && file.owner === userId; }
});
ContactsFS.fileHandlers({
default1: function(options) { // Options contains blob and fileRecord — same is expected in return if should be saved on filesytem, can be modified
console.log('I am handling default1: ' + options.fileRecord.filename);
console.log(options.destination());
return { blob: options.blob, fileRecord: options.fileRecord }; // if no blob then save result in fileHandle (added createdAt)
}
});
